| Abstract: | Mining the ore in pillars above the mine-out area comes down to the security of production, mining methods and putting in practice. In order to evaluate the stability of top terrane and wall rock precisely, the stress relief method by overcoring was used to measure the in-situ stresses in Sanshandao Gold Mine of China. In this measuring, the technique of improved hollow inclusion cells was adopted which can actualize complete temperature compensation. From the measuring results, a distribution model of in-situ stress was established, and the in-situ stress distribution rule of Sanshandao Gold Mine was analyzed. The results show that the in-situ stress field of Sanshandao orea relies mainly on horizotal stress and accords with the crustal movement rules of China. |
